Before you create the etcd-operator make sure you setup the necessary rbac rules if your Kubernetes version is 1.6 or higher.
$ kubectl create -f example/deployment.yaml
etcd operator will automatically creates a Kubernetes Third-Party Resource (TPR):
$ kubectl get thirdpartyresources NAME DESCRIPTION VERSION(S) cluster.etcd.coreos.com Managed etcd clusters v1beta1
Note that the etcd clusters managed by etcd operator will NOT be deleted even if the operator is uninstalled. This is an intentional design to prevent accidental operator failure from killing all the etcd clusters. In order to delete all clusters, delete all cluster TPR objects before uninstall the operator.
$ kubectl delete -f example/deployment.yaml
Delete leader election endpoint
$ kubectl delete endpoints etcd-operator
